Waves on circular paths

Mar 03, 2022 (Nanowerk News) Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as "magnons" in analogy to the electron, could transport information much more easily than electrical conductors. An international research team has now made an important...

low-cost, non-toxic and more efficient

Mar 03, 2022 (Nanowerk News) Researchers supported by the EU-funded HEINSOL, PREBIST and DISCOVER projects may have found a much better alternative to current solar power technology with a new type of ultra-thin solar cell. Made from nanocrystals containing silver and bismuth atoms, the solar cell could help to reduce...

A biodegradable and recyclable piezoelectric sensor

Mar 03, 2022 (Nanowerk News) The flip side of the convenience that electronic devices brings us, electronic waste presents a complex and growing challenge on the path toward a circular economy – a more sustainable economic system that focuses on recycling materials and minimizing waste. E-Waste is now considered the...

Optical nano-biosensor enables rapid and quantitative serological testing of COVID-19

Mar 02, 2022 (Nanowerk News) Serological tests play an important role in the surveillance and management of epidemics or pandemics, as well as in acquired immunity studies. Currently, COVID-19 serology is performed by well-established immunoassay techniques, which provide high sensitivities, but require specialized laboratories with trained personnel and processing times...

Coronal loops may not be what they seem

Mar 02, 2022 (Nanowerk News) Many coronal loops — ropey strands of plasma that scientists have long thought existed in the Sun’s atmosphere — may actually be optical illusions, according to a new paper that challenges prevailing assumptions of what we know, and don’t know, about the Sun. The research,...
